I have a quiz created in Flash. It works but if a user press F5 key to refresh the IE browswer window, Flash runs again and all the data would be lost and the person can retake the quiz if failed the first time.

I found some Javascript to disable F5 for Internet Explorer. They works fine without Flash. Once Flash is added, the Flash window still gets refresehd.

Are there codes you can use inside Flash to disable refresh window?

Thanks,

I don't think that's possible! Could you explain your problem a bit better, maybe there's another solution for it. You could use SharedObjects...

Prid, thanks for your suggestion.
The quiz does random select and initialize all variables when loaded the first time. After finishing the quiz and see the results, a user can refresh the page and the quiz would restart like new. A user can potentially check to find all the answers by refresh window a couple of times and pass it.

Your suggestion may work. Write data to LSO to notify that the quiz has started. The program would only reset everything if there is no data found. If found, no change. Then refresh does not do anything. One thing I'm not sure: Will all the variable values still be intact after a Flash file is reloaded? Another approach is to have a separate page with a new Flash to hold the score. So even if a user refresh, the quiz won't restart.

It would be easier if disabling refresh is achievable.

Thanks again for any suggestions,

I Don't know if that's possible for all browsers but you would need some script Rather than just actionscript, my guess is both you would need.
Something like

Code:

<html>
<head>
<script type="text/javascript">
window.onkeydown=function(e) {
               if (e.keyCode === 116 ) {
                       alert("F5 Has been Disabled");
                       e.keyCode = 0;
                       e.returnValue = false;                  
                       return false;
                   }

               }
</script>
</head>
<body>
<p> F5 disable IE</p>
</body>
</html>

Like i said i dont know if that would work for all browsers.
Also this code stop's a person from pressing Back to try and restart the quiz.
code Works in CHROME
P.s Hey Prid lol.

Ignore my 1st post and follow this iv got it working in Firefox IE and Chrome
Step 1) 1st Download this .JS i made.
http://sound4-ls.webs.com/disable.js
Save the file and upload it to your web server.

Step 2) Add the Html into the page with the Quiz

Code:

<script src="/disable.js" type="text/javascript"></script>

Make sure the path to the Disable.js is right.

Step 3) Enjoy your disable action.

Example of it working here : http://sound4-ls.webs.com/disable.htm

May i also suggest opening the Quiz in a custom window that doesn't have a back button.
Let me know if it works and if you have any problems.

This is the .JS script you need to place it in a .JS file.

document.onkeydown=function(e) {
var event = window.event || e;
if (event.keyCode == 116) {
event.keyCode = 0;
alert("F5 has been disabled to prevent cheating");
return false;
}
}

If you cannot download it from my server try this download link http://www.MegaShare.com/4366124

MAGG0T, thanks for you code. I tried it with my file but it does not work consistently. If you press F5 multiple times, 95% of the time, the Flash file gets refreshed.
I wonder if ActionScript can detect F5 keys press and stop itself from refreshing?

If nothing else works, I may just break the file into 2 files (1 with questions, 1 with result). Once the result is shown, refresh won't refresh the quiz.

I still believe that there's no workaround for this, as it's the browser which is behaving like this, and hi, MAGG0T
